The radiator may have debris that needs to be flushed out.
Could be a clogged radiator Could be water pump is not circulating coolant
Look at the lower or rear of radiator
Reasons Of Overheating # Insufficient coolant in system # Water pump defective # Radiator core blocked or grille restricted # Thermostat faulty # Electrical cooling fan inoperative or blade broken # Radiator cap not holding proper pressure
It is in the lower radiator hose
Yes it will.
A 1996 Pontiac Sunfire uses Dexcool coolant. This should only be mixed with distilled water, never tap water. Replace the coolant every 2 years or as needed.
whaT KIND OF COOLANT DO I PUT IN MY 2001 PONTIAC SUNFIRE Generally, the GM model vehicles, or is this case, the sunfire, use a specific kind of coolant called DEX-cool extended life engine coolant. It is orange-ish in color and most of the time GM specific. i have a 01 sunfire, 2.2 liter myself, and on my car frame, i have a sticker that says "Use only DEX-cool engine coolant....". Hope this helps!
Coolant is all pretty much the same from manufacturer to manufacturer. Check your owner's manual to find out the right mixture for your Sunfire
damaged or faulty radiator If coolant is "pouring" out of the radiator with no damage evident, could be stuck thermostat, especially if it happens soon after starting car. Could also be blown head gasket if pouring out of the fill tube with cap off.
it's getting too cool, really
Open the hood on your Sunfire. Remove the radiator cap from the radiator overflow bottle. Turn the engine on in the Sunfire, and let the engine run for no less than 15 minutes. Set the dials on the heater control panel to full fan speed, full heat, and front defrost positions. This will speed up the processes of heating the engine to full temperature. Removing the radiator cap and performing these procedures will allow the pressure in the engine to build up. As the pressure gradually increases, the weight of the coolant will force air bubbles out through the radiator overflow bottle hole. This process is called bleeding the cooling system. Turn the engine off when you notice that there are no more bubbles coming from the radiator overflow. Top off the radiator overflow bottle with fresh coolant. Use 50/50 diluted, universal coolant to fill the overflow. Replace the radiator cap when the reservoir is at the "Full" mark. http://www.ehow.com/how_7734216_bleed-system-Pontiac-sunfire-22l.HTML
First make sure the radiator is full of coolant ;this is where the heat comes from. If it is full , then change your cars thermostat. The stat is located at the lower end of the top radiator hose within the water outlet. That should do it.
